Channel Characterization and Simulation Modeling of Diffuse Scattering in Highway Mobile Communications

摘要

In this contribution, the characteristics of diffuse scattering are analyzed and modeled for vehicular propagation channels in highway environments. The response of a Vehicle-to-vehicle (V2V) channel is composed of discrete specular path components and diffuse scattering components. Numerical simulations are conducted through two different V2V scenarios. The power spectra of the diffuse components, induced by the diffuse zone along the highway, are analyzed in delay, Doppler and angular domains. This investigation also indicates the necessity of jointly modeling the discrete specular path components and diffuse scattering components in highway propagation environments.
